The abyss descend

Civilization is destroyed.

Lei Mingkai, the last survivor, took the last civilized core of the hometown world - the Long Toothed Lion to shuttle through many machine battles in time and space, looking for ways to revive the hometown world and launch a revenge war against the abyss.

Facing the abyss that destroyed countless civilizations, the lone survivor roared from his heart

"The stars can be destroyed! The universe can be destroyed! But civilization will never be destroyed! Even if the world comes to the end because destruction, civilization will last forever!"
